Accurate rebuilding of sagittal plane radian measure for treatment of thoracolumbar vertebrate fracture: a comparative study

Background. The purpose of this study was to compare the outcomes of patients with second hammertoe deformities who underwent correction using either joint resection arthroplasty, proximal interphalangeal joint (PIP) arthrodesis without osteotomy, or interpositional implant arthroplasty. Methods. Medical records from patients who underwent second PIP correction from July 1999 to December 2008 were retrospectively reviewed. A total of 114 patients (136 second toes) were the basis for this retrospective comparative study. The average final follow-up with weight-bearing radiographs of the 136 procedures at the second toe was 53.8 months. Results. All 3 groups had significantly reduced VAS scores postoperatively (P < .01). Also, all groups had significant radiographic correction in the average measured lateral angle of the second PIP joint (P < .01). However, the interpositional implant group had significantly corrected the second PIP joint in the axial plane, with an average postoperative anterior-posterior (AP) angle of 2.9° (P < .01). The postoperative AP angle was also significantly different compared with the postoperative AP angles of the other 2 groups (P < .01). Discussion. Our study confirms that all 3 techniques provide adequate pain relief and radiographic sagittal plane correction. However, interpositional implant arthroplasty provides significant radiographic correction in the axial plane. Levels of Evidence: Therapeutic Level III, Retrospective comparative study

Level Of Evidence

Background: The anatomy of the syndesmosis is variable, yet little is known on the correlation between differences in anatomy and syndesmosis reduction results. The aim of this study was to analyze the correlation between syndesmotic anatomy and the modes of syndesmotic malreduction. Methods: Bilateral postreduction ankle computed tomography (CT) scans of 72 patients treated for fractures with syndesmotic disruption were analyzed. Incisura depth, fibular engagement into the incisura, and incisura rotation were correlated with degree of syndesmotic malreduction in coronal and sagittal planes as well as rotational malreduction. Results: Clinically relevant malreduction in the coronal plane, sagittal plane, and rotation affected 8.3%, 27.8%, and 19.4% of syndesmoses, respectively. The syndesmoses with a deep incisura and the fibula not engaged into the tibial incisura were at risk of overcompression, anteverted incisuras at risk of anterior fibular translation, and retroverted incisuras at risk of posterior fibular translation. Conclusions: Certain morphologic configurations of the tibial incisura increased the risk of specific syndesmotic malreduction patterns. Level of Evidence: Level III, comparative study.
